To all whom it may concern:

Be it known that I, Ronenr MmnLn, a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a, new and 5 useful Improvement in Smut-Sheet Attachments for Sheet-Delivery Mechanisms, of whichthe following is a specification.

This invention relates to means for carrying a supply of smut sheets on the sheet delivery mechanism of a printing press or other apparatus where such an arrangement would be useful, and it has more special reference to that type of smut sheet devices which are connected directly with reciprocating sheet deliveries and move back and forth with the delivery as the latter performs its function of receiving and delivering the printed sheet.

The invention has for one of its important objects to provide an improved and efficient means for preventing the pile of smut sheets from shifting or sliding out of place as the some is moved back and forth with the sheet delivery.

Another object of the invention is to provide improved nnd efficient means whereby smut sheet attachments for large sheets will be given adequate support upon the apparatus. And a still 1" urther object of the invention is to provide improved means whereby the pile of printed sheets with the smut sheets alternating therewith may be replaced upon the smut sheet table or attachment and the dry printed sheets conveniently removed from such pile each time the table makes a.

reciprocation, leaving the smut sheet accessible to the hand of the operator or feeder in readiness to beremoved and placed upon the printed sheet last delivered upon the piling table of the sheet delivery mechanism.

The invention consists in certain features of novelty in construction, combination and arrangement oi parts by which these obj ccts and certain other objects which .Will hereinafter appear are attained, all as fully (1escribed with reference to the accompanying drawings,

and more particularly pointed out in the claims.

In the said driiwings,-ligure 1-is a side elevation of a portion of a printing press and sheet delivery mechanism embodying this invention and showing the delivery at the limit of its return stroke; Fig. 2 is a. similar view showing the delivery at the limit of its delivery stroke;

of the uses-to which it may be put, it is shown in connection with a reciprocating sheet delivery of a'printing press, but so for us the function of the parts of the appsratus which constitute this invention is concerned, the portion of the printing press shown may represent any other apparatus by which sheets of paper or other mate 5 rial are treated, printed, or coated in such a way as to make it necessary or desirable that when they are delivered therefrom upon a. piling table theyshould be separated by smut sheets to prevent them from sticking together. 7

l, 2 are the arms which operate the sheet delivery mechanism, and which mechanism in this example of the invention comprises a reciprocating carriage 3, having rollers 4 running upon tracks 5 at the sides of the app21 rs tus, and which carriage supports the fingers or any other means not necessary to illustrate for receiving and supporting the sheet during the delivery operation, the carriage 3 being connected to the arms 1, 2 by rods or links 6. The carriage 3 is also provided with anti-friction rollers 7, upon which test the forward ends of two rails 8, upon which is supported the smut sheet table 9, the lower edges of the rails 8 being formed of longitudinal grooves 10, as shown in dot-ted lines in Figs. 1 and 2, in which the anti-friction rollers 7 engage, as shown in. lull lines in Fig. 4. The carriage 3 is thus made to support the forward end of the smut sheet table 9, and the rear end of this table is supported by rollers 11 running on supplemental tracks 12 extending rearwardly from the usual tracks 5 ordinarily employed in this class of sheet delivery mechanisms for supporting the carriage 3. The rear ends of the tracks 12 may be supported in any suitable way, as by feet 13 resting upon brackets 14.

The smut sheet table 9 derives its reciprocating motion also from the arms 1, 2, by means of links 15, piyotcd at 16 to the arms, and at 17 to the table 9, butit will be soon that the links 15 are considerably shorter than the links (3, so that while the table 9 will reciprocute in unison with the carriage 3, its travel will be slower and less in length than that of the sheet delivery,

and as a consequence the tendency of the pile of smut sheets 18 supported upon the'teble 9, to shift or slide 0d the table by the momentum acquired will beprevented.

As the arms 1, 2 move forwardly the table 9 moves with the carriage 3, end as the motion of the table 9 decreases and that of the carriage 3 continues to the end of the sheet dclivcry StlOkc, the rollers 7 which support the rails 8 of the table, move forwardly in the grooves 10 of said mils, thereby permitting the table 9 to come to rest without interfering with the operation of the sheet delivery mechanism.

It will also be seen that the rear ends of the supplemental rails or tracks 12 are considerably elevated, so

that as the smut sheet table moves to the limit'of its return stroke its rear end is elevated above the horizon- 14. In adevice for the purpose described, the combina- L011 0t 1 reciprocating sheet: delivery. a smut sheet tahie supported i cohnection with said delivery and movable therewith, a piling table for the printed and smut sheets arranged below the delivery, and a piling table for the dry' sin-ms arranged above the plane 01! the smut sheet table.

154 In a device for the purpose described, the combina tiun of a reciprocating sheet delivery, asmut sheet table :mppm'ted thereover and movable therewith, and-:1 dry 10 $110M; piling tahle supported above the plane of the smut sheet table at a point in the length of the stroke thereof at the end of the summit sheet table when the latter is at the limit of its receditig or return stroke.

In witness whereof, I have hereunto set my hand this 27th day ol' July 1905, in the presence of the subsurihing 15
